    .SYNOPSIS...
    A STRONG LOW PRESSURE SYSTEM AND ITS ASSOCIATED COLD FRONT OVER
    THE CENTRAL AND SOUTHERN PLAINS WILL MOVE SLOWLY TOWARD GEORGIA
    THROUGH TUESDAY. THE FRONT WILL PASS OVER THE STATE ON WEDNESDAY.
    A STRONG LOW LEVEL JET WILL PROVIDE ABUNDANT GULF MOISTURE IN
    ADVANCE OF THE STORM WHICH WILL COMBINE WITH THE OROGRAPHIC
    EFFECTS OF THE GEORGIA MOUNTAINS TO ENHANCE THE RAINFALL.
    .PRE-EXISTING CONDITIONS...
    RAINFALL AMOUNTS OF 2 TO 4 INCHES HAVE OCCURRED OVER CENTRAL GEORGIA
    DURING THE PAST TWO WEEKS WHICH WERE 150 TO 300 PERCENT OF
    NORMAL. CONSEQUENTLY...MOIST SOIL CONDITIONS EXIST WITH SOME AREAS
    STILL WET AND JUST RECOVERING FROM WELL ABOVE NORMAL STREAMFLOWS
    AND FLOODING. THIS WILL ALLOW ANY HEAVY RAIN TO BE QUICKLY
    ABSORBED...THEN RUN OFF INTO NEARBY STREAMS...CREEKS AND RIVERS.
    WHILE SOME AREAS OF EXTREME NORTH GEORGIA HAVE HAD BELOW NORMAL
    RAINFALL FOR THE PAST FEW MONTHS...THE HEAVY RAINFALL AMOUNTS
    EXPECTED WITH THIS STORM SYSTEM WILL QUICKLY SATURATE THE SOILS
    AND PRODUCE RAPID RUNOFF INTO NEARBY STREAMS...CREEKS AND RIVERS.
    .IMPACTS...
    ISOLATED FLASH FLOODING WILL BE POSSIBLE IF THE HEAVY RAIN
    REPEATEDLY MOVES OVER THE SAME AREA. ALSO...STORM DRAINS AND DITCHES
    MAY BECOME QUICKLY CLOGGED WITH DEBRIS AND CAUSE EXTENSIVE STREET
    FLOODING AND ROAD PONDING.
    MINOR FLOODING OF SOME OF THE LARGER CREEKS OR RIVERS IS MORE LIKELY
    WITH THE EXPECTED STORM TOTAL RAINFALL AMOUNTS IN NORTH AND CENTRAL
    GEORGIA AND SHOULD BE MONITORED CLOSELY.
    THIS WEATHER SITUATION IS BECOMING MORE CERTAIN WITH EACH MODEL
    RUN...SO STAY ALERT FOR POSSIBLE FLOOD WATCHES AND FUTURE WARNINGS.
    KNOW WHAT TO DO IF A WARNING IS ISSUED AND YOU LIVE NEAR A CREEK
    OR RIVER.
